TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Mar. 1915.

Application filed August 22, 1913. Serial No. 786,108.

To all whom it may concern: I

Be it known that I, ARTHUR J. Bnroos, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type- Writin Machines, of which the following is a speci cation.

My invention relates to typewriting machines, and more particularly to the paper feed mechanism.

The main object of the invention, generally stated, is to provide paper feeding mechanism, which is simple in construction, inexpensive to manufacture, and eflicient in use.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations-of devices, set forth in the following description and particularly pointed out in the appended claims.

In the drawings, Figure l is a transverse sectional view of one form of platen carriage equipped with paper feeding devices constructed in accordance with my inven tion, the paper feeding devices being shown in normal or operative position. Fig. 2 is a like view of the same, with parts omitted and parts broken away, this view showing the paper feeding devices released. Fig. 3 is a front elevation of the parts shown in Figs. 1 and 2. I

As shown in the present instance, the carriage comprises a traverse or guide bar 1 having end plates or brackets cured thereto and projecting upwardly The end plates are united tie-rod 3 and are apertured at t to receive a platen shaft 5, the usual finger wheels being secured to the end of the platen shaft. A rotative platen 6 is mounted on the platen shaft and is provided with the usual platen heads 7 and 8, the latter of which is formed with line spacingratchet teeth 9. A single piece sheet metal combined paper table and apron 10 extends from the rear side of the platen beneath the same and to the front thereof where it terminates at 11 below the printing line indicated by the dotted line X. The combined paper table and apron therefore extends from the introductory side of the platen to the front thereof just beneath the printing line, and in its normal position each adjacent i's.disposcd, as shown in Fig. 1, with the forward. edge of the paper apron bearing against the platen. The paper apron i apertured at 12, ears 18 being struck up and extending forwardly from the paper apron at the endsof each aperture 12. These cars are perforated for the reception of a pivot rod ll on which are mounted paper feed rollers 15, the latter being arranged at the front of the platen and'below the printing line. As shown, a roller is received hetn pair of ears l3 and extends through the associated aperture 12 in the paper apron and into contact with the platen or the paper thereon.

The combined paper table and apron it) is mounted for bodily movement fore and aft of the machine in the foll ,;-wing manneri A cross rod 16 extends through the length of the carriage in the rear of the paper l and is connected thereto by straps i? are riveted to the paper apron at cross bar is flattened at its ,ends and turned upwardly to form supporting arms or links 19 which are pivoted by shouldered pivot screws 20 to theinner sides of the end plates 2 of the carriage. The arms 19 constitute in effect substantially vertically disposed parallel links upon which the reaiwend portion of the combined paper table and apron is supported through the cross bar 16. The forward end portion of the paper table and apron is supported by a single centrally dis; posed sheet metal link, designatedus whole by the reference numeral This link is also substantially vertically disposed and is pivoted at its lower end on a pivotrod which is received inbearings in sheet metal bracket secured to the cross bar 1 by a screw 24. The upper end of the sheet metal link is turned aroundthe pivot rod is of the feed rollers, as indicated at It will be seen that this single she t metal link 21 has a comparatively narrow pivotal hearing at its lower end, whereas the bearing portions at the upper end of the link are widely separated in order to provide a coinparatively broad pivotal hearing at the upper end of the link where it'makes connection with the paper apron. The construction and arrangement of the links on which the combined paper mounted are such that the combined paper table and apron is adapted to receive a bodily shifting substantially horizontal table and apron is movement fore and aft, of'themachine from the position shown-.iri Fig. 1 to that inclicated in Fig. 2.

The forward edge of the paper apron and the paper feed rollers 15 are normally maintained against the platen, or the paper thereon, by two leaf springs each of which is designated as a whole by the reference numeral 26. The upper end of each spring is secured by a screw 27 to the associated. end plate 2, whereas the lower end portion of each spring is offset inwardly, as shown at 28 :in Fig. 3, and is then extended forwardly and upwardly, as at 29 (Fig. 2), to the forward 'side' of the cross bar force of each spring is exerted rearwardly on the cross bar to force the combined paper table and apron to the position shown in Fig. 1 and cause the paper feed rollers and the forward edge of the paper apron to bear against the platen. In order to release the feed rollers and the paper apron it is merely necessary to exert a forward pressure against the upper curved edge 30 of the paper table in the direction of the arrow in Fig. 1 and thus effect a movement of the member 10 and the parts carried thereby from the position shown in Fig. l-to that indicated in Fig. 2.

I have provided a simple and eiiicient paper finger construction whichis so combined with the' paper apron that the paper fingers may be simultaneously released when the feed rollers are thrown off, as indicated in Fig. 2. The paper finger construction comprises a bar'or support 31 which is angular in cross section and which is provided with integral bracket arms 32 by which the bar may be secured to the member 1 of the carriage by screws 33'. The main body portion of the bar, which extends substantially throughout the length of the carriage, is disposed at an inclination, as shown in Fig. 1. The paper fingers are each designated as a whole by the referencenumeral 34: and each paper finger and its supporting portion are formed from "a single piece of spring sheet metal. The lower end of each paper finger is formed with a supporting or engaging portion 35. This portion partly surrounds the supporting bar 31 and conforms to the contour thereof so as to prevent the paper finger from turning on the bar but to enable it to be adjustable along the bar longitudinally of the platen. There is -a spring pressure exerted by each paper finger against the platen or the paper thereon, and'this, with the frictional resistance between the supporting portion 35 of each paper finger and the bar on which-it is received, is sufficient to maintain the paper fingers against accidental displacement from the positionsto which they may be adjusted longitudinally of the platen. From an inspection of Fig. 1 it will be seen that the 16. The

in which the feed rollers I 15 may be received. This is in order to provide a clearance between. the paper feed rollers and the paper fingers which extend upwardly in front thereof, so that the paper feed rollers 15 will offer no obstruction to the adjustment of the paper fingers longitudinally of the platen.

It will be understood from a comparison of Figs. 1 and 2 that although the paper fingers 34: are supported independently of the paper apron, they extend adjacent to the forward edge 11 thereof so that when the latter is moved from the position shown in Fig. l to that indicated in Fig. 2 the paper fingers will be simultaneously flexed and thrown ofi, irrespective of the positions to whichthey may be adjusted longitudinally of the platen. The feed rollers, the forward edge of the paper apron and both paper fingers will, therefore, be simultaneously released from contact with the paper.

While I have shown my invention embodied in the present instance in a front strike typewriting machine in which the type bars 37 are adapted to strike against the front face of the platen, it should be understood that the invention may be em- 'iOdIBd. in many styles of typewriting' machines and that various changes may be made within the limits and scope of ,my invent on.

From the foregoing description it will be understood that I have provided a paper feed mechanism which is simple in construction, which is cheap to manufacture, and which is efiicient in use, the construction comprising but few parts, most of which are formed from sheet metal and can be readily assembled.

What I claim as new and desire to secure by Letters Patent, is p 1.
